But instead of adding a back door to their servers, the companies were essentially asked to erect a locked mailbox and give the government the key, people briefed on the negotiations said. Facebook, for instance, built such a system for requesting and sharing the information, they said.

The data shared in these ways, the people said, is shared after company lawyers have reviewed the FISA request according to company practice. It is not sent automatically or in bulk, and the government does not have full access to company servers. Instead, they said, it is a more secure and efficient way to hand over the data.

FISA orders can range from inquiries about specific people to a broad sweep for intelligence, like logs of certain search terms, lawyers who work with the orders said. There were 1,856 such requests last year, an increase of 6 percent from the year before.

In one recent instance, the National Security Agency sent an agent to a tech company’s headquarters to monitor a suspect in a cyberattack, a lawyer representing the company said. The agent installed government-developed software on the company’s server and remained at the site for several weeks to download data to an agency laptop.

In other instances, the lawyer said, the agency seeks real-time transmission of data, which companies send digitally.

The technology companies, which participate knowingly in PRISM operations, include most of the dominant global players of Silicon Valley. They are listed on a roster that bears their logos in order of entry into the program: “Microsoft, Yahoo, Google, Facebook, PalTalk, AOL, Skype, YouTube, Apple.” PalTalk, although much smaller, has hosted significant traffic during the Arab Spring and in the ongoing Syrian civil war.

Dropbox , the cloud storage and synchronization service, is described as “coming soon.”

The PRISM program is not a dragnet, exactly. From inside a company’s data stream the NSA is capable of pulling out anything it likes, but under current rules the agency does not try to collect it all.

Analysts who use the system from a Web portal at Fort Meade key in “selectors,” or search terms, that are designed to produce at least 51 percent confidence in a target’s “foreignness.” That is not a very stringent test. Training materials obtained by the Post instruct new analysts to submit accidentally collected U.S. content for a quarterly report, “but it’s nothing to worry about.”

Even when the system works just as advertised, with no American singled out for targeting, the NSA routinely collects a great deal of American content.

We analyze the effects of a court ruling in France and several court rulings in Germany on VC investment in cloud computing firms in these countries. These court rulings were seen as negatively affecting the development of cloud computing, and our findings confirm this view by showing that these rulings regarding the scope of copyrights had significant, negative impacts on investment. Specifically, we find that VC investment in cloud computing firms declined in Germany and France, relative to the rest of the EU, after the French and German rulings. Our results suggest that these rulings led to an average reduction in VC investment in French and German cloud computing firms of $4.6 and $2.8 million per quarter, respectively. This implies a total decrease in French and German VC investment of $87 million over an approximately three year period. When paired with the findings of the enhanced effects of VC investment relative to corporate investment, this may be the equivalent of $269.7 million in traditional R&D investment.

Reason for rejection is the fact that if the user does not have Dropbox application installed then the linking authorization is done through Safari (as per latest SDK).

Once the user is in Safari it is possible for the user to click "Desktop version" and navigate to a place on Dropbox site where it is possible to purchase additional space.

Apple views this as "sending user to an additional purchase" which is against rules.

Dropbox's CTO and cofounder, Arash Ferdowsi, did not like Dropship. His reaction was swift. According to the project’s creator, Wladimir van der Laan, Ferdowsi contacted him soon after and requested "in a really civil way" that he take the project off of github. van der Laan complied.

Soon after Ferdowsi contacted me directly, sending what I now assume is the same “really civil” request he sent to others. He requested that I not only remove the archive from Dropbox but delete my posts on Hacker News, which at that point included the fake DMCA takedown. He outlined his objections, that Dropship reveals their proprietary client-server protocol and that it could be used for piracy. He told me that the DMCA takedown was a mistake and reverted the lockdown on my public files.

First of all, attempting to protect a proprietary protocol is going to get them nowhere. His argument implied security by obscurity. Security by obscurity falls completely flat on its face in this case since their client can be analyzed by anyone with the proper skills and could be deciphered again.

Second, dealing with piracy is the responsibility of Dropbox. It’s not the problem of an innocent hacker who wrote some useful code that could benefit legitimate users and advocates the use of his software for “sharing photos, videos, public datasets, git-like source control, or even as building block for wiki-like distributed databases.”
